Description

Technical Field

[0001] The utility model relates to the relevant field of defect detection equipment, in particular to a plastic mold injection surface defect detection device. Background Art

[0002] Injection molding is a processing method used in batch production of certain parts with complex shapes. Although the structure of the mold may vary due to the different types and properties of plastics, the shape and structure of plastic products, and the type of injection machine, the basic structure is the same. Due to the variety of plastics and the complex process of producing injection molded products with plastic molds, various defects are inevitable on the surface of the injection molded products after production. Injection molded products are often produced in batches, and the injection molded products on the assembly line are highly similar.

[0003] In the prior art, surface defects of injection molded products are detected by defect detectors. However, it is not convenient to freely flip and adjust the rotation angle of the product to be inspected during the inspection. Manual assistance is required to adjust the position of the product during the inspection process, which will greatly reduce the inspection efficiency of the device and increase the manual labor. If the product is not rotated and flipped for inspection, it will lead to deviations in product inspection quality. Therefore, we need to upgrade and transform the existing technology to overcome its problems and shortcomings. Utility Model Content
